Drug Addictions: Transcendental Meditation compared to other methods
Decreased Use of Illegal Drugs
A meta-analysis of all relevant research studies found that those who had been using illegal drugs showed a substantial and long-lasting reduction in the use of such drugs after learning the Transcendental Meditation Programme. This reduction in drug use was significantly greater than the effect of standard prevention programmes for reducing drug use.
